Hp d530c pc won't boot, push power button and fans start and run for two seconds then stop and power on light blinks red. I thinking either mother board or power supply, I unplugged the HD and had the some results. The box has no add on cards in it. Thanks James

D530 cmt won't power on, I took out the cmos battery overnight, after putting it back in the next morning, computer still won't power on. Green lights just constantly blink. Any suggestion or solutionD530 cmt won't power on, I took out the cmos battery overnight, after putting it back in the next morning, computer still won't power on. Green lights just constantly blink.

I think its your CPU IC. Its overheating and the auto shut safety sequence is being activated and hence this problem. It can also be that the temperature settings in your CMOS setup has been set to a wrong / low setting wherein the PC shuts off even if your CPU warms up a little. Check that by going into CMOS settings. Only after confirming that, have your motherboad checked & also your HDD for a short in the power supply section. Perhaps a capacitor is leaky or short or a diode is short. Send it to an authorised repair center.

This means your PC is doing a Thermal Shut down, the CPU is getting to hot, this means the fan is not running at all or fast enough, or is dusty causing loss of cooling to the CPU.

To fix this open the case look at the fan if its running as it gets louder I would say in your case it is, you need to remove all the dust from the fan and the heatsink I use a small USB fan from poundland (UK) this should stop this error.

mine does that when it's in stand-by mode. I just push the power button and it comes on....

Assuming you've already tried that....push and hold the power-button down for 5 seconds and the power SHOULD go out. *IF* it does not, then disconnect the power cord in the back for 1min....then reconnect and try to boot. If it *DOES*, then do the same...unplug the power cord for 1min and reconnect and boot.

When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

If there was recent hardware added to it or RAM then try removing it and boot up. You can try resetting the RAM. You can also check all cables and power within the case to make sure everything is connected properly. Listen for the fan on the PC, if the fan doesn't start up then it could be an overheated mother board. Beeps can mean a number of different things. If there's no error on the screen then it probably isn't getting further then the BIOS. I hope that helps.

one light is for hardrive activity , the other is to show the power is on.. the flashing one is most likely the power light as most computers will tell you when thier ill....the beeping is an error code and should be in some pattern EG: Power LED blinks red twice, once a second, followed by a two second pause. Or something like that. Take note of the pattern and repost it here, then we can give you a specific area to look at.
